DRYING APPARATUS.

Application filed September 27, 1919, Serial No. 328,800. RenewedJanuary 13, was.

To all whom-it may concern Be it known that I, THOMAS C. LAZIER, acitizen of the Dominion of Canada, residing in the city of Belleville,Canada, have invented a certain Improvement in Drying Apparatus, ofwhich the following is a specification.

In certain United States patents to Sey' mour W. Bonsall, and notably inhis Patent Number 1,047,734, dated December 17th, 1912, there aredescribed and claimed certain forms of rotary driers depending foroperation upon the principle of subjecting the materials to be dried, tothe action of a current of air which is compressed by being forcedthrough narrow passages between the surfaces of the articles to bedried.

My present invention relates to a novel and improved form of dryingapparatus for applying the same general principle of operation as isutilized in the Bonsall patent aforesaid to the drying of variousmaterials and more especially to drying shingles. The invention in itsnarrower aspects relates to an improved package of shingles particularlyadapted to be inserted within my improved drier, as well as to thespecial su ports for such package which forms a etachable element inmy'apparatus.

The invention is illustrated in a preferred form in the accompanyingdrawings, wherein Figure 1 is a plan view of my preferred drier, showinga portion broken away to re veal the interior, Figure 2 is a frontelevation of the drier, Figure 3 is a side elevation of the containingframe showing the same partly filled, Figure 4: is a. perspective viewof one supporting track, Figure 5 is a plan view of a shingle-supportingunit, Figure 6 is a side elevation of the same showing a portion of aside bar removed, and Figure 7 is an end view of one side of the same.

My improved drier is composed of a plurality of elements each comprisinga scoopshaped intake passage or fine and a drying passage or flueforming a continuation of the intake flue and directed away therefrom.Two or more elements of this kind are mounted so as to balance eachother upon a revoluble mounting which, in the form shown, is set upvertically. In the present Instance I have shown the apparatus aspreferably equipped for drying shingles, but the invention in itsbroadest aspect is not limited to this modification.

In the preferred form shown my drier is composed of two air boxes, 10and 11, mounted symmetrically upon the shaft 12, which may be revolvedby any suitable means, as for instance, the gears 13 and 14. Each boxterminates on one side of the shaft 12 in a scoop-shaped intake, 15, 16,and this leads through a sharply curved air collecting flue having itscontinuation in the drying flue whose top is shown broken away in thelower part of Figure 1. In the preferred form shown, the outer side ofthe drying flue is made in the form of a door 17, hinged at 18, so that,when this door is swung open. the material tobe dried may be loadedthrough this doorway from the platform 19. W hen closed, this door maybe confined by any appropriate means, as for instance, the locks and 21,on the upper and lower outer corners of the door, engaging the roof andfloor of the drier, respectively. I

In order to carry out the purpose of the invention in accordance withthe principles of operation set forth in the Bonsall patent aforesaid,it is necessary to so dispose the shingles or other material treatedthat narrow passages are formed through which the large volume of aircollected is forced to travel in a compressed condition. For practicalpurposes it is also important that means be provided whereby thematerial and its supporting medium shall be easily balanced in opposingmembers or elements. For these purposes, and to save time and labor inpreparing and loading, I have devised the removable container shown inmy drawings.

This container comprises a number of independently separable supportingunits, carried symmetrically upon a movable frame. The preferredsupporting unit is shown in Figures 5, 6 and l (paral 35 themselves.

This unit comprises parallel flat vertically set side plates 22, 23,mounted upon wheels 24, which are preferably flanged, as shown. The endsof the side plates are joined by 5 parallel, horizontally set, flat endplates 25,

rods are preferably passed through holes in the end plates, being bentback into hori zontal position at their extremities as shown best at 28in Figures 6 and 7.

The holding rods 27 are placed at such a distance apart as to makecontact with opposite faces of the tapering shingles 30 near the buttsthereof, when these shingles are dropped sharp edge downward betweensaid rods. It will thus be seen that the loading of the shinglesinvolves the minimum of time and labor, since it is only necessary toplace each supporting unit in turn in front of the chute delivering theshingles, sharp edge down, through the spaces between the holding rods.The side edges of contiguous shingles should touch, and there will thusbe formed a number of vertical passages, very narrow in cross section,separated by walls constituted by the shingles These passages extendfrom end to end of the supporting units.

The units thus loaded are next united in a container frame in such amanner as to bring the narrow air passages in one unit into line withthose in the units above and below'the same; thereby constructing aseries of flat narrow air passages side by side.

from top to bottom of the container, and consequently from top to bottomof the drying flue in the box' 10 or 11, into which containers of thiskind are fitted. Figures 1 and 2.) v

The preferred container framecomprises a-base 31 on wheels 32, carryingfour corner See 60 posts 33, side posts 34, and top bars 35 and 36.Carried by the posts 33 and 34 re- ,spectively, are transverse tracks37, parallel to the axes of the wheels 32.

The supporting units, having been loaded as described. are placed in thecontainer by setting their wheels 24 upon the tracks 37 and pushing themin until their frames come against the stops 38. tracks are thusoccupied the entire container will be divided by narrow flat verticalpassages running transversely with relation to the direction in whichthe wheels 32 of the container are set.

It will thus be seen that, when the door 66 17, of the drying flue onone side of the When all the messes drier is opened, and a containerthus loaded is rolled from the platform 19 into the flue, filling itboth horizontally and vertically, the result will be the formation of acomposite drying flue whose elementary passages are of the desirednarrow character, set edgewise to the direction of the air current inthe flue, and whose walls are constituted by the shingles to be dried..-As already remarked, the structure of the container is such that allthe structural material takes the form of thin rods or plates setlengthwise and edgewise to the current. The round holding rods,moreover, present a mere line of contact with the shingles, and there ispractically no part of the shingle surfaces shielded from the air.

When both sides of the drier are thus loaded, the doors 17 are closedand secured, and the entire drier is then caused to revolve in thedirection of the arrow in Fi ure 1. This revolution will cause the air00%- lected by the two scoops to be forced in a compressed state at ahigh rate of speed through the narrow passages above described. Asdescribed in the patent to Bonsall above specified, this will cause theshingles to be subjected, not only to surface evaporation, but'to anexhausting effect exerted at the eternal orifices of the moisturecontaining capillaries or pores of a nature familiar in machines forexhausting electric lamp bulbs and in other connections.

Various changes may be made in my 2111- paratus without departing fromthe scope of my invention, and I do not limit myself to the detailsherein shown and described.

What I claim is 2- 1. Drying apparatus comprising a. plurality ofrevolubly mounted elements balanced a'ronnd their center of revolution,each element comprising an intake scoop and flue and a drying flueforming a continuation of the same and directed away from the intakeopening.

2. Apparatus of the character set forth in claim 1 hereof wherein theelements are mounted upon a vertical shaft provided with means fordriving the same.

3. Apparatus of the character set forth in claim 1 hereof, wherein theouter wall of the drying line is provided with a door adapted to permitloading of the material therethrough.

4. In combination with the other features of a revoluble drier, aseparable container comprising a wheeled frame and independentsupporting units adapted to be inserted in said frame, wherein thecontainer is supplied with pairs of tracks, and wherein the supportingunits are provided with wheels fittingupon said tracks.

5. pparatus of the character set forth in .claim 4 hereof, wherein theinde endentsupporting units are constructed 0 plates menses 6. Asupporting unit for carrying shin-' gles, comprising parallel holdingrods set at such distance apart as to touch the two faces of a shingleinserted sharp edge downward between them, and means for supporting saidrods wherein round rods are used which are supported by a trance madeofplates set edgewise with respectto the direction of the rods.

7. in drying apparatus of the general character described, a compositedrying flue comprising a group of narrow elementary drying finesseparated by walls composed of superposed rows of parallel shingles allset edgewise to the expecting direction of the air current.

In testimony whereof I have hereto set my hand on this 23rd day ofSeptember 1919.
